<p>A rotational angle sensor constituted of a stator provided with a single-phase excitation winding and two-phase output windings and a rotor having a salient pole and a rotary electric machine comprising this sensor. The two-phase output windings are wound around teeth of the stator. Since the number of turns of each two-phase output winding is the number of turns determined by virtually defining m-phase windings (m is an integer of three or more) and converting the number of turns of the m-phase windings into the number of turns of two-phase windings is smaller than that of the m-phase windings. Therefore, the structure is simple, and the manufacturing process is easy.</p> |
